#CAR-DQOR LOCK.

SPECIFICATION forming part of Letters Patent No. 294,513, dated. March4, 1884.

' Application filed AugustlS, 1883. (No model.)

To alZ whom it may concern:

Be it known that I, JAMES SHARK'EY, of Honey Creek, in the county ofHenry and State of Indiana, have invented a new and Improved Oar-DoorLook, of which the following is a full, clear, and exact description.

My invention consists of a latch-bar pivoted to the car-body below thelower back corner of the car-door, and reaching up at an inclination ofabout forty-five degrees to' a point about midway between the twovertical edges of the door, where it is connected to the door by anangular slot in it and a stud-pin attached to the door, so that the barforms a latch for fastening the door shut without being locked, and aslide-bolt and lock are contrived with said latch-bar to lock the dooralso, the arrangement of the latch-bar being such that a pull on it inthe direction for opening the door will so disconnect said bar from thelocking-stud as to free the bar from the stud and allow the force of thepull jarring open when unlocked,

to be expended in opening the door, with which the said bar will thenswing freely to allow the door to open, making avery simple andsubstantial locking device, which will effectually prevent the door fromshaking or all as hereinafter fully described.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in

' which similar letters of reference indicate corthe latch-bar withoutbeing responding parts in all the figures.

Figure l is a side elevation of part of a car with a door provided withmy improved latching and locking device, the door being open.

Fig. 2 is a side elevation of the same with the door closed and securedin that position by locked; and Fig. 3 is a side elevation of the samewith the door closed, latched, and also looked. V i

The door a is arranged in the slideways b and between the stop-cleats cand d, in the usual or any approved manner, and is provided withhand-holds e, .to facilitate the sliding of it forward and backward.Under the lower back corner of the door I connect a latch-bar, f, to'the body of the car byastrong. pivot, 9, said latch-bar f being longenough to reach to the middle of the door between the vertical edges onan inclination of about up on the stud-pin h,

' doorand the slot being in the bar. Parallel to the part 2' of the slotand crossing the part j between slot i3 and the head of pivot-stud h isa range of staples, 7c, in which a lockingbolt, Z, is to be placed whenthe door is to be locked, the bolt having a small staple. m, that willslide under staples 10, over which staple m a link, a, pivoted to barfat 0, drops, to prevent the bolt from sliding when the hasp of apadlock, p, latch-bar f, being thus prevented from rising so that thedoor may slide-by the stud running along slot 1;, forms a substantiallocking-bar to the door; and it will be seen. that when not .locked thebar serves the purpose of a latch to hold the door shut, and the gravityof the bar will prevent the door from working loose by the shaking andjarring of the car. I The improved fastening device is applicable to anysliding door or gate as well as to car-doors, and I propose to employ itfor any such sliding door.

The latch-bar f has a handle, q, for a con-- venient means of lifting itto unfasten the door, and at the same time to slide the door back.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. The combination, with a sliding door, of a latch-bar, f, pivoted to apermanent support at the lower backcorner of the door and connected tothe door at the middle, or thereabout, by a stud-pin, h, in the door andthe angle'slot z j in the bar, said bar being inclined, so that itgravitates to a rest at the upper end of slot j on. the stud h, andthereby forms a latch to fasten the door shut, substantially asdescribed.

2. The combination of a slide-bolt, I, having staple m for a lock, 10,with the latch-bar f, having staples 7c and link 1%, pivoted to a isinserted in staple m. The a support and connectedto the door, as shownand described, the said staples k and bolt Z being located between thepart z of the slot and the stud h, to lock said stud in the upper end ofpart j of the slot, substantially as described.
